charles fishman

Charles FishmanSeven years ago, Dean Amhaus, the president and CEO of The Water Council, was looking for a way to bring fresh energy to the annual Water Leaders Summit. Dean knew the work of journalist Charles Fishman and had heard him talking about water on NPR, so he asked Fishman if he’d be interested in finding an all-new way of staging a conference.

That’s how the Water Leaders Summit came to have its original, energizing style. Every panel tackles an urgent topic in the storytelling format that is now a hallmark of the Water Leaders Summit. Fishman draws stories and examples from experts that they’ve never shared before — and he makes sure no question goes unasked.

Fishman started his reporting career at the Washington Post, where he was part of the team that investigated the Challenger space shuttle disaster. He is the author of three New York Times-bestselling books, most recently “One Giant Leap,” the story of how America put people on the moon in the 1960s. His book “The Big Thirst” is the bestselling book about water in a generation, and a standard for people trying to understand how best to tackle water problems. He lives in Washington, D.C., with his wife, also a journalist.
